A: BMS hardware shai hkat ai lam gaw pack manu a 12% daram hpe galaw ai. Lahkawng-shift bungli galaw ai shaloi, shawng ningnan shaning laman hta, lata hte yu reng ai lam hpe shayawm ai hte, shi hkrai shi charge galaw ai lam hpe hkyen lajang ai hku nna, bai gram lajang lu ai. Single-shift galaw ai shaloi, nambat ni hpe shawng galaw ra ai.
San: Ya nga ai AGV sanghpaw li ni hpe CAN-enabled battery ni hte bai gram lajang mai na kun?
A: Rai na re, AGV controller hta CAN port nga ai rai nna, battery a protocol hpe madi shadaw ya ai rai yang. Moi na controller ni gaw mawdaw langai $300-400 daram hte gateway hardware ra na re. Anhte gaw quote n galaw shi yang, htuk manu ai lam hpe jep yu ga ai.
